After a recent upgrade, some users are having issues where they are unable to see the menu icons.

If you have visited the mapping page before, your web browser will have kept some of the information from the old page to help it to load faster when you return to that page. The information is 'cached' by the browser.

To clear the cache, with the mapping page open, refresh the page by holding CTRL then press F5. The menu icons should then appear.
